"I saw the one of me washing a Trans-Am automobile in the driveway shirtless with tattoos all over myself and out there," Biden said with a smile. He took some issue with the story, though. "By the way, I have a Corvette-- a '67 Corvette-- not a Trans-Am."

Biden laughed that he's probably not supposed to encourage the mocking, but he said he still gets a kick out of it.

"Most people refer to me who know me, and even in the press, of being a little bit square," Biden said. "And now, I'm the philanderer. I think it's hilarious, the stuff they do on me."
